Lesson 3: Bio-Geosphere Flashcards
an individual living thing, such as bacterium, fungus, protist, plant, or animal
organism
3 ways to classify an organism
systematic
taxonomy
classification
scientific study of the diversity of organisms and their evolutionary relationships
systematic
science of naming, describing, and classifying organisms
taxonomy
arranging organisms into groups based on their similarities, which reflect historical relationships and lineage
classification
Swedish Botanist who is often called the Father of Taxonomy who developed a system for naming, ranking, and classifying organisms
Carolus Linnaeus
2 Kingdoms: Plantae and Animalia
Mid 19th century
Ernst Haeckel (German Biologist) introduced 3rd Kingdom: Protista
1866
introduced 5 Kingdoms based on cell structure and nutrition: Plantae, Animalia, Protista, Fungi, and Prokaryote. (1969)
RH. Whittaker
Carl Woese (University of Illinois) studied RNA of bacteria and proposed 2 groups: (1970s)
Archaebacteria and Eubacteria.
3 Domains and 6 Kingdoms
today
the 3 domains
archaea
eubacteria
eukarya
Archaebacteria,
extremophile, without
peptidoglycan
archaea
Bacteria with peptidoglycan
eubacteria
plants, animals, fungi,
protist
eukarya
six kingdoms
- plantae
- animalia
- protista
- fungi
- eubacteria
- archaebacteria
(phylum) internal skeleton e.g. bear
chordata
(phylum) exoskeleton e.g. insects
arthropoda
(phylum) soft unsegmented body e.g. mussels, oysters
Mollusca
(phylum) e.g. worms
Annelida
(class) humans, dog, pig
Mammalia
(class) frog, salamander, axolotl
Amphibia
(class) snake, lizard, crocodile
Reptalia
(class) insects (6 legs)

(class) octopus, squid
Cephalopoda
(class) birds
aves
order
carnivora
primata/primates

Developed by Linnaeus.
Simplified scientific
classification
Binomial Nomenclature
Utilization of the same
resources by organisms of the same (intraspecific) or of different (interspecific) species living together in a community when resources are insufficient
Competition
One organism makes its living at the expense
of another
exploitation
an interaction where
one species kills and
consumes another
species
Predation
kills and consumes its prey
Predator
animals that is
hunted and killed for
food by a predator
prey
a symbiotic relationship
where one species
benefits from the
relationship and the
other is harmed
parasitism
lives on the tissues
of their host, often reducing fitness but not generally killing
it
Parasites
an insect whose larva consumes its host and kills it in the process
Parasitoid
a symbiotic relationship
where different species
benefit from the interaction
mutualism
a symbiotic relationship where one species benefits from
the interaction and the other species is neither harmed nor
helped
commensalism
